Abstract:
We studied the expression of MHC-I and MHC-II molecules and ICAM-1 in cultured human myoblasts in response to IL-1beta, IL-4, IL-6, IFN-gamma and LPS. IFN-gamma, LPS and IL-4 greatly increase MHC-I molecule expression. MHC-II molecule expression is induced only by IFN-gamma. Membrane ICAM-1 and mRNA expression are absent under basal conditions, but can be induced by IFN-gamma, IL-1beta, IL-4, LPS and IL-6 with different efficiencies and time-courses. Soluble ICAM-1 secretion can be induced to a different extent by all cytokines. Our study shows that the expression of adhesion-related molecules in muscle is finely regulated by these cytokines.

Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.
